it's what this election is about. for mr. romney, that was then. now on that, a number of issues, he seems to be trying to downplay what he once described as his severely conservative record and recast himself as more centrist on some issues. the shift began a moment after this handshake in denver. he was insistent on government regulation, education and health care. >> how would repeal it? >> it's a lengthy discussion, but number one, preexisting conditions are covered under my plan. >> that assurance is misleading, and later on an adviser had to clarify what mr. romney actually meant. under mr. romney's plan, he said, preexisting conditions would only be covered for people who already have insurance to begin with, but are changing jobs and, therefore, health insurance plans. that's not what most people think of when it comes to preexisting conditions. ironically, the health care law that mitt romney signed in massachusetts and remains in place, it does allow for preexisting conditions whether they have health insurance or not. we will be watching
